Tall/whom tmag/ concern:

Be it known; that I, Jael; Minen` S'rorvnn,

va. citizen of' the United States, .residing at Chicago, intlie county` of Cool; and State Illinois, have invented certain new and use-v ful Improvements .in Shock Absorbers for Vehicles, ont which the, following isa speci-v either. direction. substantially proportional to the. amplitude ot movement of said spring connected members, and which will permit substantially free, unopposed movement of the springs withinv normal working limits.

Another object is to` provide an inexpen-v sive, incemplex and eiiicient structure for the purpose described.

Another object is generally to improve shock absorbers. y

Other objects and advantages of. the invention will readily appear. from a considerv ation of the 'following description when taken in conjunction with the drawings, wherein Fig. 1 is a side elevation ot the shock absorber connected between two spring-connected vehicle members.

Fig. 2 is a section taken on Fig. l.

Fig. 3 'a section online 3-3 ot Fig. 1.

In all the views the same reference charaeters are employed to indicate similar parts.

In the shock absorber about to be described there is a sufficient and suitable resista-nce interposed by the deviceV at the in'- stant when the recoil or rebound occurs. .In the operation oit springs, as they are usually line 2-2 oi' Vapplied to vehicles, the tree and forced vibration causes excessive spring action and thus a sott spring willhit bottom and then The tree vibration is the effect which occurs when a relatively Vsoit spring is about to expand suddenly after compression and forced vibration is that which is caused by impressed force compressing the spring. It Jfree and forced vibra-- tions are properly able results following the recoil or rebea-.id are effectively taken care of. A shock abrelates to vimprovements in controlled the obj eetion i. soi-ber ftliat il willpve,rniit a relatively soft VSpring to,y move` uninterruptedly within a reasonablelimitfot its maximum movementand interposes `a resistance proportional to the move-ment excessive of its normal morement, 'in either direction, will produce easy smooth running of the car. i

In the 'drawings which I have lused ter illustrating `my invention', 5 Vis apart of 'the frame of an automobile and 6 isthe axle ot the running gear or chassis. Between the] members and Athefshock absorber Z is' shown to be connected. y

Theshock absorber 7 is normally rectangular in shape, as shown in Fig. 1, and censists of four link members 8, 9, a-nd 11. -The link members 8 andlO are double, each consisting of the blades 12 and 13 that are curved or bent inwardly towards each` other, as more clearly-shown in Fig. 2. At and between the ends ot the members 12 and 13,l the members 9 and 11 are respectively ineluded. The membersfQ and 11 are transversely tapered'. or made wedge-shape, corresponding to the inclinationl of the blades 12 and 13 et the mei'nbers A8' and 10. The' `members 12 and 13 are connected at their ends tothe members 11 and 9, respectively, by the bolts .14 and 15, and the Vbolts 15 are conencted to clips 16 and 17, respectively, 4

that are secured to the sprung and unsprung members of the vehicle; the frame 5 being the sprung member and the axle of the running gear 6 the unsprung member.

Villien the axle 6 approaches more nearly to the frame 5 than shown in Fig. v1, wedgecletorces the slioelr absorber membersto-V gether near the bolts 15, the actionin 'beth eases being substantially the same; that is to say, the resilient resistancethus opposed by the shock absorber is proportional tothe displacement ot its members; er more Acorrect-ly stated, is proportional to the reboundv .l shape members 9 'and 11 enter the space bel tween the members l2 and 13 and tend to 'n Vtween the spring connected parts of the vehii or compression of the spring due to the major inequalities ofthe roadway over which the vehicle is passing. K

To add to the resilient effect of the link members or blades 12Vand'13, spring rings 18 maybe placed between the head and nut of the bolts 14 or 15. The members of the shock absorber are preferably made of the best quality of spring steel so that the plates are capable of considerable latitude of'inovement or vdisplacement when forced out of their normal positions by the links 9 and 11. in the event that greater elasticity or resiliency is required, spring rings 18 may be in-Y cluded'between the head and the nut of the bolts by which the members are pivoted, and 4if it is desired that the resistanceV of the springs when moving Yin one direction be interposed'by the shockabsorber to a greater extent than the resistance interposed when the spring is moved in the opposite direction, the spring rings 18 may be placed upon appropriate bolts for producing this varying` effect. Y

in the drawing the spring 6 is shown pivotally connected to thel aXle by any suitable means, and at one end as. at 19 it -is Y similarly connected to the frame member 5.

bodiment of'my invention for the purpose.

of clear disclosure, it will be manifest to persons skilled in the art, that many changes maybe madek 1n the general arrangement `wedgeshape plate, the latter members hav` ing their ends pivoted to the respective ends of the other members and between the plates thereof, thereby forming a' parallelogram whereby resistance to movementM ofy two members toward and from the other two members, in both directions, is imparted.`

2. A shock absorber comprising two pairs of like members, one member of a pair of like members comprising` two overlying flat vspring plates curved inwardly toward each other; each of the other mem ers comprising a wedge-shape plate, the latter members having their ends pivoted to the respective ends of the other membersl and between'the plates thereof, thereby forming a parallelograin whereby resistance totmovementof two members toward and from the other two members, in both directions, is imparted, the arrangement beingsuch that slight initial movement is permitted` without interposing resistance due Vto the formation of the plates.

In testimony whereof I hereunto sub@ es i'
